Re: [maemo-developers] Packet Telephony?
Hi, please have a look at http://tapioca-voip.sourceforge.net. It is a work in progress. And also a short description of how it works at: http://marciom.blogspot.com/2005/10/voip-with-tapioca.html I like Tapioca's distributed approach - nice use of DBus IMHO. :) I'm really curious though, why you would use GStreamer for VoIP - you say on your website that: Many of the existent open source VoIP has a media subsystem of its own, which means that transport protocols and codec implementation are inside the application's code. That' s why I believe that a great feature in Tapioca is that it uses gstreamer to provide audio codecs, device handling and RTP streaming. This gives a lot of extensibility to the multimedia layer. I'm not sure that makes sense to me since on the n770 the DSPs are sinks themselves - at least if this page: http://maemo.org/pipermail/maemo-developers/2005-September/001217.html is correct. No other open source telephony apps use GStreamer (that I know of) and it looks like you'd have to hack it to make it work on an n770 and a desktop from the same code base... assuming you had software plugins for the codecs for GStreamer (do those exist?). I do like getting the RTP framework of GStreamer, but for VoIP that seems like a heavy-weight option just for RTP. Thoughts?

I'm not sure, but seems that they use Gstreamer's pipeline, so you can
do something like:
source - decoders={ speex, h323, ... } - sink={alsa, oss, ... }
AFAIU Tapioca would do the SIP connection setup and then assemble this
pipeline for you.
Maemo have a special sink called mp3sink that short circuit
decoder=mp3 and sink=alsa(?), that avoids calls back to main ARM cpu,
consuming less cycles.

As Marcio already said, we could develop a media subsystem but this way we were going to again duplicate efforts, what i think IMHO is not a good thing. So we decided to use gstreamer that seems to be going to be used as default multimedia framework on linux desktops. And another reason is that we want to concentrate on VoIP stuff as the multimedia part we can easily handle using gstreamer.

Re: [maemo-developers] Packet Telephony?
Greg, there is a Vancouver, BC company, Counterpath (formerly Xten) that has a SIP compliant VOIP softphone. They have a no-cost download of a stripped down version of their SIP Softphone, which can be run on Microsoft Windows, Linux, or Apple OS X. Here is the url to the www page for the download: http://www.counterpath.com/index.php?menu=download Here is the url to a press release from earlier in the year announcing the Linux version of the X-Lite product: http://www.counterpath.com/news/20050516.pdf I don't know whether or not the Linux version comes with the source code in the .tar.gz file available from their www site. The product seems to be fairly well regarded judging by their customer base. Check out their customer base at: http://www.counterpath.com/index.php?menu=Customers Best Regards, John Holmblad Televerage International GSEC Gold,GCWN Gold,GGSC-0100,NSA-IAM,NSA-IEM (H) 703 620 0672 (M) 703 407 2278 (F) 703 620 5388 primary email address: [EMAIL PROTECTED] backup email address: [EMAIL PROTECTED] ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
